This thing is a tank. I will admit, I think Toolcraft makes awesome BCG's and they probably make 75% of the BCG's out there, other companies have Toolcraft make them and they just put their logo's on them. However the Sharp's Xtreme BCG is the Cadillac of bolt carrier groups. It is amazing how snug it fits yet cycles so smoothly. Pair this with a Radian Raptor charging handle and you have the easiest charging AR out there, just like butter. Two thumbs up on these BCG's, this is the standard for high-end AR builds. I call this thing Mil-Spec ++++, it is beauty and the beast.

I don't think you can buy a better bolt carrier group and the DLC is AWESOME, Runs smooth and is easy to clean.
BUY ONE, DRIVE IT & you will agree.

They are the best BCG, buy one you won’t disappointed.best BCG for AR 15,highly recommended!

When I set out to build my "Bucket List" custom "Recce Rifle" AR, I researched parts and reviews for almost a year...This BCG came out on top and I couldn't be happier.

Excellent product, went together easily and went bang every time. I used it on a 13.7 inch, mid length gas, A5 buffer pistol.
